23 and scared to have child with anyone

My life isn’t the best but I live a decent life I save money pay all my bill on time,and eat well.

I’m getting to that age where kids are apart of discussion and my so who I been dating for a year ask me to have his child but I am so terrified that he will mistreat me , leave me, or just drag me thru hell because you know I’m vulnerable and if I leave I will not have that support I need then I will be struggling to make ends meet each month.

I’m so scared to become a mother to a child because of how men flip the strict. The man I am talking he is a good father. Always Calls me everyday speaks to me for hours. But in the beginning he was very inconsiderate and mean with his actions. He finally changing and becoming softer with me.

He is 34 and I am 23

Anyone have advice for me
